Energy from Hydrogen

Most headlines after the recent UK Budget focused on taxation and increased governmental borrowing. Yet there were many supportive mentions in the Chancellor’s speech for the UK’s prominent role in developing clean energy solutions, including green hydrogen. Rachel Reeves confirmed that the UK is preparing to grant revenue support of up to £2.3bn for 11 green hydrogen projects that total 125MW in scale.

This summary paper is intended to raise understanding and awareness of hydrogen’s potential, the science involved, and examples of diverse businesses in the UK seeking to commercialise it.

Making a cleaner world

The global supply / demand picture for hydrogen is rapidly evolving as the world shifts toward cleaner energy solutions. Hydrogen is viewed as a critical component of this transition. The International Renewable Energy Agency (IRENA) states that the global production of hydrogen now stands at 75 Mt/yr of pure hydrogen, with an additional 45 Mt/yr as a mix of gases. 

Looking forward, the International Energy Agency (IEA) estimates that already announced projects could increase production by 50% by 2030 and meet up to 10-12% of global energy demand by 2050.

Hydrogen can be produced from a variety of resources, including renewables, nuclear energy, and natural gas (with carbon capture). This flexibility offers countries the ability to diversify their energy sources and reduce dependence on fossil fuel imports, enhancing energy security.

By far the largest current demand for hydrogen comes from heavy industrial sectors such as steel, cement, refineries, chemical plants, and others. In addition, when renewable sources like wind and solar produce excess electricity, hydrogen can in turn be produced via electrolysis and stored for use in the future generation of electric power.
